Detailed explanation-1: -The differences in the characters (or traits) among the individuals of a species is called variation. Variations can be in the morphological appearance (phenotype) or the genetic makeup (genotype) of an organism. It can be caused by change in the DNA sequence (mutation), random mating, etc.
Detailed explanation-2: -The differences in characteristics between individuals of the same species is called variation . Some variation is passed on from parents to offspring, via genes during reproduction. This is inherited variation. Some variation is the result of differences in the surroundings, or what an individual does.
Detailed explanation-3: -Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Genetic variation is a result of subtle differences in our DNA?.
